what's Caravan?

Caravan is an open-source, stateless multisig wallet tool for Bitcoin, enabling users to coordinate and recover multisig wallets directly in a web browser without relying on centralized services. Primarily designed as a recovery mechanism for Bitcoin vaults and loans, it supports air-gapped hardware wallets and ensures users retain full control over their funds even if service providers like Unchained Capital become unavailable. The tool facilitates PSBT (Partially Signed Bitcoin Transactions) coordination across multiple keys in setups like 2-of-3 multisig.

Caravan forked, creating a new 2/2 multisig wallet with dramatic usability improvements.
